How many kilometers should a new car run before high-speed driving?

[MacDaniel]

A new car can be driven at high speeds after the break-in period. It is not recommended to drive at high speeds initially for a new car; the maximum speed should not exceed 100 km/h, and the maximum RPM should not exceed 3000. High-speed driving before the first maintenance: It is best to perform high-speed driving after the first maintenance of the car. The first maintenance of a new car mainly involves checking the vehicle's operating conditions, ensuring the torque of various screws and the safety of fluid levels. This makes driving more reassuring, so it is recommended to perform high-speed driving after the first maintenance. Avoid high-speed driving before an oil change: When driving a new car at high speeds, it is important to choose the right time and pay attention to the quality of the engine oil. Avoid high-speed driving before an oil change. During high-speed driving, the engine operates at high RPMs, leading to maximum mechanical wear. If the oil quality is poor, it can directly affect the engine's performance. Additionally, the first batch of engine oil contains more impurities, which can increase engine wear during operation.
